Re: Computer help request.
The screen saver is usually the big culprit on this scenario. But other programs accessing the hard drive will cause it too.
Go to the Start button, then click the Run button. Type msconfig and press the enter button on your keyboard.
When the msconfig program starts click on the Startup tab. This will show you everything that is started and running when you boot your computer. If you don't know what something is, don't turn it off else your computer may get worse. Turn off things you don't need or want. Norton and Zone Alarm especially.
Reboot your computer and try defrag again.
Hope this helps
